Unit BTU [IT]
Name British thermal unit
Category Energy
Details BTU (British Thermal Unit) is a unit of energy used in the field of heating, ventilation, air conditioning, and understanding energy consumption in various processes. The BTU is based on the Imperial System and has been historically used in the UK, US, and other countries adopting the British system of units.

The BTU is defined as the amount of heat required to raise the temperature of one pound (approximately 0.454 kg) of water by one degree Fahrenheit (approximately 0.56 degrees Celsius). Specifically, the IT [International Table] indicates that it is the International Steam Table version which is the most widely accepted and used standard for BTU.

In the field of Energy, BTU is used to measure heat generation, cooling loads, efficiency of heating systems or appliances, fuel consumption, and other thermal processes. You can often find BTU ratings specified for appliances such as furnaces, air conditioners, refrigerators, and water heaters, as well as in comparing different types of fuel sources.

To provide a better understanding across the different units of energy, 1 BTU [IT] is equivalent to approximately 1055.06 Joules, or 0.00029307 kilowatt-hours (kWh).
